This article aims to introduce some common NEON optimization skills which come from development practice. …

Jan 9, 2013 · ARM® NEON™ technology is a SIMD (single instruction multiple data) architecture extension for the ARM Cortex™-A series processors. It can accelerate multimedia and signal processing algorithms such as video encode/decode, 2D/3D graphics, gaming, audio and speech processing, and image processing.

Sep 11, 2013 · Coding for Neon - Load and Stores; Arm's Neon technology is a 64/128-bit hybrid SIMD architecture designed to accelerate the performance of multimedia and signal processing applications, including video encoding and decoding, audio encoding and decoding, 3D graphics, speech and image processing.

Feb 14, 2019 · Arm Cortex‑M processors, naturally our first thought was to just add the existing Neon technology. However, the need to support a range of performance points within the area constraints of typical Cortex‑M applications meant we had to start from scratch.

NEVADA models a simplified ARM CPU with NEON and ARM registers, and a linear memory space is available for loading and storing further data. The whole machine state can be saved and restored later, which is useful for sharing code snippets. The state can also be saved as a link, so the saved code snippets can be embedded inside any webpage.

Oct 13, 2022 · Previous generations of Arm instruction sets (e.g. the older Armv7-A) included 32-bit Neon instructions. However, the 64-bit variants include both 32-bit and 64-bit execution states, which means both the previous generation and the newer Neon instructions are available depending on which mode a process is being executed.

Sep 11, 2013 · 利用NEON技术编写代码. ARM NEON™ technology is widely used for multimedia optimization. The SIMD architecture of NEON technology makes it very suitable for many compute intensive modules in multimedia codecs such as filtering, de-blocking etc. This blog explores effective coding techniques to enhance performance of an audio/video codec.
